Identify parts of an expression using mathematical terms (sum, term, product, factor, quotient, coefficient) and describe one or more parts of an expression as a single entity.

Patterns, Functions, and Algebraic Structures

- Make claims about relationships among numbers, shapes, symbols, and data and defend those claims by relying on the properties that are the structure of mathematics
Algebraic expressions can be used to generalize properties of arithmetic

Write, read, and evaluate expressions in which letters stand for numbers.
